Pushed around 3300 fps from a 280 Ackley to be specific. What is this bullet capable of? Max range on deer/antelope/black bear/elk? I've never cross sectioned one myself, but have heard on many occasions it has a thicker jacket than the 140 Ballistic tip. This bullet is scary accurate in my 280AI..........all groups with this bullet and H4831sc are in the .156"-.210" range. For comparisons, the 140's (Ballistics and Accubonds) are a consistant 1/2" group. I know I'm probably being a little anal in the accuracy department, but with those 120's I feel I could "shoot a hummingbird in the lips".
